HAIR-PIN.

Specification of Letters Patent.

Patented Mar. 19, 1912.

Application filed May 20, 1911. SeriabNo. 628,508.

2' 0 all whom it may concern:

Be it known that I, FREDERICK Hnnns'r, a citizen of the I United States, residing at Danville, in the county of .'Verinilion and State of Illinois, have invented new and useful Improvements in Hair-Pins, of which the following is a specification.

This invention relates to hair pins and the object of the invention is the provision of a device of this character which may be conveniently inserted without mussing the hair and which, by its peculiar structure and inherent features, will lock itself in position against accidental removal.

Heretofol'e, hair pins of this general type have been constructed but they were either difficult of insertion, mussingjthe hair or breaking the same, or they were easily arred outof position.

It is the object of this invention to avoid these difiiculties, and broadly speaking, the device consists in a pair of pins each having a wavy formation connected. together so that the crest of one wave coacts with a similar crest upon the adjoining leg of the other pin, whereby receptacles for the hair are formed, the legs abutting at these points to lock the hair in these receptacles, and the legs having suflicientresiliency to permit the separation thereof for insertion.- v

Further objects of the invention will appear as the following specific description is read in connection with the accompanying drawing, which forms a part-of this application,. and in which 2- Figure 1 is a side elevation showing one form of my device. Fig. 2 is a similar view Fig. 3 is a detail side elevation showing a further modification.

Referring to the drawing and more particularly to Fig. 1, l'and 2 represent separate yoke-shaped members, the heads 3 and 4 of which are connected together by a sleeve 5 which.is bent around the heads so as to clamp the same together. The head 3 of the member 1 conforms to the head-it of the'member 2 for a short distance and then takes a sharp inward bend. as shown at 6, on eitherside. The legs 8 which form a continuation of the head and have parallel a'xes extending outwardly from the inward bend 6 on what may be termed a long wave 9. At the end of this wave a short inward wave 10 is'formedwhich produces, with the next succeeding long wave '11, a crest or contacting point 12. This formation is carried out throughout the majority of the length of the leg which, at the end, is providcd with a straight portion 13. The opposlte pin 2 curves around inwardly on a long wave 14 where it connects with the legs 7 and then extends outwardly on a short wage 15 and then inwardly on a long wave 16. The short and long waves 15 and 16 form crests or contacting points 17 which are adapted to abut the contacting points 12 and form, with the long and short waves of the opposite legs 7 and 8, the hair recep taclcs or spaces 18. The inward waves 14, or in other words, the continuation of the head 4 has a portion thereof lying outside of the leg 8 and a portion'thereof lying inside of the leg 8 crossing the same at the points marked m. By ressing inwardly upon the head 4 of the legs 7 will be moved toward each other and away from the. legs 8, thus separating the legs 7 and 8 and permitting the convenient insertion of the hair pin into the hair.

In the modification shown in Fig. 2,"the

legs 19 and 20 are formed into semi-circular waves 21 at their upper ends which cross each other to form a circular receptacle 22 and have their heads 23 and 24 twisted together, as shown at 25, the head 24 being arranged on the outside of the head 23 and the legs of this pane-tossing the legs of the opposite pin and l'ying.within the same, so that, by' pressure upon the head 24, the legs 20 are forced inwardly toward each other and separated from the legs 19, thereby pr- .mitting the convenient insertion of the hair' The modified form of connectiomshown in Fig. 3, embodies weldingthe heads together, as shown at 26, the legs being con structed in a similar manner to that shown in Fig. 1.

Having thus described the invention, what I claim as new is:--

1. A device of the class described comprising a pair of U-shaped hair pins'having inner and outer heads connected'together and their legs crossed, the legs of the outer head lying within the legsof the inner-head.

2. A device of the'class described comand their legs crossed andcontacting at separated points throughout the length, the legs of theouter head lying Within the legs of the inner head.

3. A device of the class described comprising a'pair of substantially yoke-shaped hair pins having their heads connected together,

the legsof the pins being crossed so that the' legs of the outer head lie Within the legs of the inner head, said legs being provided with a plurality 'ot' long and short Waves throughout their lengths, said waves producing contacting crests, the crests on the inner legs abutting those on the outer legs and forming hair receiving spaces, said legs having inherent resiliency, and the outer 'head adapted to be contracted so as to bring the inner legs together to separate them from the outer legs.

In testimony whereof I aflix my signature in presence of two witnesses.
